What kind of measurement method is used by Bernd insulation monitor?

Adaptive pulse signal (AMP) measurement method (German Baender patented technology, European patent number EN654673B 1) superimposes an adaptive pulse signal between the IT system and the earth. By comparing the waveforms of the sending signal and the returning signal, the relative distributed capacitance and frequency of the load in the system are measured, and the amplitude and width of the measurement pulse are automatically adjusted, thus successfully eliminating the high-frequency interference and DC interference of various medical diagnosis and monitoring equipment.
